Dwell time in tablet compression
WebThe Dwell Time Calculator built by LFA is designed to help you work out how long your tablet is under maximum compression. Understanding this will help you scale up from small scale R&D to batch production of your tablets. The dwell time is calculated in the following way: Where: dt = dwell time (milliseconds) Dhf = head flat diameter ... WebThey do not allow the user to replicate key principles affecting production-sized presses, such as centrifugal force, mechanical feeder behavior and dwell time. Its biggest advantages are: Small size Ease of operation Low noise levels Compression feasibility Advantages of the Rotary Tablet Press Machine
